. To all whom 'it 'may concern:

and shown in the accompanying drawings which form a part thereof-i Heretofore I have constructed and commercially employed drying machines in which the textile materials have been conveyed through the drying room or chamber by conveyers or aprons and in which chamber or room said textile material was treated to currents of heated air circulated by means of fans and caused to be circulated repeatedly over the textile material and those portions oi said drying air which become heavily laden with moisture are allowed to escape and fresh air admitted into the circulationto take its place in a very gradual manner. The objection to this method lies in its slowness because ofthe high hygrometric state of the circulating air, and also because of the necessity of power to drive the fans or blowers.

The object of my present invention is to overcome the above objections, by providing a method of circulation which only necessitates the air passing once over `the textile 'material and eliminating all necessity of blowers or circulating fans. l

My invention consists of a drying room in which the textile material is to be placed to be dried, combined with-means to supply a current oi heated air to the upper portion of'said drying room, and a heated chimney having a communication between its bottom and the bottom portion of the drying room whereby the moist Or damp air is drawn off by the suction of the chimney.

The chimney may be heated by the same source of heat which heats the incoming air or otherwise as desired, and if desired a single heated chimney may be used in connection with several drying rooms or chambers. f

My invention also comprehends details of construction, which together with the features above specified, will be better understood by reference to the drawings, in which:

Figure l is a sectional elevation of my improved drying machine for textile material; Fig. 2 is a cross section of the same; Fig. 3 is a longitudinal sectional elevation of a modification of my invention; Fig. 4 is a cross section of the apparatus shown in Fig. 3; Fig. 5 is a sectional elevation of another modication of my invention; and Fig. 6 is a plan view showing one rchimney for several drying chambers.

A is the drying room and may be of any suitable construction, being provided with the endless aprons or conveyers H guided aboutdrums or wheels .T and I as shown in Figs. 1 and 2, or adapted for poles M for yarn N as shown in Figs. 3 and 4 or in any other manner adapted to receive and subject the textile material, of whatever character it may be, to the drying action of the air.

In the construction shown in Figs. '3 and 4 there is a perforated oor K and doors L for access into the chamber.

Arranged to one side of the drying chamber A is a heating chamber B provided with heating coils C. Air enters through a door E at the bottom and becomes' heated in passing upward over the steam coils C and in the heated state passes through the passageway D into the top of the drying room or chamber A as shown. The heated air then descends through or over the textile materials and in its moist or saturated condition passes to the bottom of the chamber and into the flue F which communicates with the bottom of the chimney G which is heated by the steam coils C or otherwise. The heat of the chimney causes the damp air to become heated and to rise up through said chimney and escape at its top. By means of this heated chimney there is a draft set up through the drying chamber which causes a continuous ilow of heated air into and through the drying room or chamber A.

In the constructions shown in Figs. l, 2, 3, and 4 the same coils C heat the chimney and inflowing air,t but in Figs. 5 and 6, additional heating means C are employed for heating the chimney G. While steam coils are the means employed it will be evident that any other suitable means may be used in lieu thereof..

In Fig. 6- the moist air from several drying rooms pass by flues G to a single chimney Gheated by the heating means C, and if desired, the draft of the chimney may be assisted by a blower R. The fiues Gj are preferably heated by the heating coils ofthe several chambers in a similar manner to what is shown in Figs. l to 4 before passing to the chimney.

Broadly considered, my invention comprehends means for supplying heated currents of fresh air to the upper portion of a drying room, causing the heavy damp air to be sucked from the lower portion ofthe drying room and removed rom further Contact with the textile materials to be dried, and controlling the entrance of the air to the drying room to suit the requirements. i

In practice the sliding door E Controls or regulates the circulation of the air through the drying chamber and also the density of the air within said chamber.

My improvement may be applied to any form of drying room or chamber now in use, such as those having conveyers or aprons, those adapted for use of poles or those for' use of trucks for example.

The details may be modied if so desiredwithout departing from the spirit of my invention.

`the damp air from the bottom of the drying chamber.

v Having now described my invention, what I claim as l new and desire to secure by Letters Patent, is:-

1. In` a closed drying apparatus, a drying' chamber in which the textile material is dried, combined with a heating chamber communicating at its top only with the top of the drying chamber and provided with an inlet for outside air at its bottom, heating coils within said heating chamber, and a chimney heated by the coils in the heating chamber open only at top and bottom and having its bot# tom opening into the lower part of the drying chamber.

2. In a drying apparatus, a drying chamber in which the textile material is dried, combined with'a heating chamber communicating at its top with the top -of the drying chamber and provided with an inlet for air at its bottom, -heating coils within said heating chamber, a chimney having its bottom opening into the lower part of the drying chamber and extending adjacent to the heating coils for heating the chimney'and producing therein a draft for drawing 3. In a drying apparatus, a drying chambercombined with endless aprons forI conveying the textile material through the drying chamber, a heating chamber con1u1unieating at its top with the top ofthe drying chamber and provided with an inlet for air at its bottom, heating coils within said heating chamber, and a heated chimney having its bottom opening into the lower part of the drying chamber.

4. The combination of two` or more drying chambers through which heated air is caused to pass, an externally JOHN H. LORIMER,
